H. SHLAMUWITZ. VENTILATOR. APPLICATION FILED SBPT.9,1908.

I 0 n 3 WW INVENTOI? Jiymen filamau/z'iz By ATTORNEYS HYMEN SHLAMOWITZ, or NEW YORK, N. Y.

VENTILA'IOR.

To all whom it may concern; I

Be it known that I, HIMEN SHLAMOWITZ, a subject of the Czar ofRussia, and a resi dent of the city of New York, borough of Manhattan, county and State of New York, have invented a new andImproved Ventilator, of which the following is a full, clear, and exact description. 7

Thisinvention relates to ventilators, and more particularly to devices of this class adapted to be placed in windows, or the like, to permit the entrance of pure air into rooms without creating drafts.

Specifically, the invention relates to a ventilator having a sash adapted to be arranged in a window or other opening, and itself pre-v Senting an opening,.ahood arranged at said opening of said sash and having a hood frame at an angle with the sash, anda pivoted closure arranged to be positioned at said opening or against said hood frame, said closure itself having a pivoted, transparent window, which can be opened in either position of the closure, the hood having a perforatedpart, which permits the entrance of air into a room, but prevents the same from carrying with it dust or the like.

An object of the invention is to provide a simple, inexpensive and durable ventilator for use-in connection with windows or other openings in buildings or like structures, which is so constructed that in a certain arrangement of the parts, air can enter the room freely, but in an upward direction, that is, in 'a direction towardsthe ceiling, the air at the same time being screened to prevent the entrance of dust, dirt, or the like.

A further object of the invention is to provide a device of the class described, which has a closure ada ted to be arranged in a. plurality of positions and itself having a transparent window adapted to be arranged in a plurality of positions, sothat the amount of opening presented by the ventilator can be varied. Y The invention .consists in the construction and combination of parts to be more fully described hereinafter, and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate correspondingv parts in all the views, in which r Figure 1 is a front elevation of an embodiment of my invention, showing the venti- Speeification of Letters Patent.

lator closed; Fig. 2 is a transverse section on the line 2-2 of Fig. 1; Fig. 3 is a longitw,

dinal section of the device' and Fig. 4 is a similar view showing certain of the parts in different positions.

. Before proceeding to a more detailed explanation of my invention, it should be clearly understood that while the same is particularly useful for ventilating rooms and the like, it can also be advantageously employed for other purposes, for example, for ventilating ships cabins or railroad or street cars. I have shown, for example, in the accompanying drawings, a form of the ventilator which includes a sash adapted to be removably mounted in a window or other opening, and encompassing a plate or member which presents the main opening proper of the ventilator. This sash is, of course, per se not an essential element of my inventiombut canbe dispensed with, the plate itself being then mounted, in any suitable manner,directlyin the window or other opening.- 7 Any suitable material can be employed in the manufacture of my invention, and I prefer to make vuse, for this purpose, of sheet metal or the like. I wish to emphasize that the invention does not reside in the details of construction shown for example herewith, butthat these details can be varied in accordance with individual preference or special conditions.

The invention consistsbroadly in the provision of a frame adapted to be mounted at an opening, a hood frame at. an angle with the first frame and connected with the same by means of a screen, or other perforated cover, the hood frame and the cover constituting the ventilating hood, and a closure movably arranged upon the frame and adapted to be positioned'against the same or against the hood frame, and itself including a pivoted, preferably transparent, window.

Referring more particularly to the drawings, I provide a sash 10 adapted to be mounted within a window frame 11, or in any suitable ventilating openin The sash 10 is preferably rectangular in orm and has a rim 12 on the inner edge, against which is positioned a plate 13 having an opening 14 therethrough. The opening 14 has preferably a straight,- transverse'loweredge, land a substantia ly semi-circular upper edge, as is shown most clearly in Fi 1. A hood frame 15, similar in form to the form of the opening 14, is arranged at the front, of the plate at an angle therewith, having the lower edge rigidly secured to the plate adjacent to the lower edge of the opening 14. The hood frame may be soldered, or otherwise mounted upon the frame.

The hood frame, at the inner side, has a laterally extending double flange 16 extending around three sldes thereof, and terminating at the edge adjacent to the plate. The latter, around the corresponding edges of the opening 14, has a similar double flange 17. Triangular sides 18 are arranged in the don ble flan cs 16 and 17 adjacent to the lower edges of screen 19, fashioned from a wire mesh or any other suitable material, is positioned between the late and. the hood frame and constitutes the ood proper. The screen terminates ad- 'jacent to the sides 18.

A closure comprising a frame 20, is pivoted upon the plate 13 by means of a transverse pivot'rod 21 arranged between the sides 18 at the lower edge of the opening 14, the frame 20 having a sleeve 22, formed to receive the pivot rod 21. The frame has 2. preferably semi-circular strengthening rib 23 extending aroundthe same, and has an opening 24, in which is arranged a window 25. The latter has a U-shaped rim 26 and a so body 27 held between the sides of the rim,

and consisting of a sheet of glass or the like. At opposite sides, the window has laterally extending trunnions 28 movably arranged in sockets 29 carried at suitable frame 20.

Y The rim 26 has projecting .flan cs 30 and 31 atjopposite sides respectively 0 the trunnions 28, and adapted to engage at opposite sides of the frame 20.

The pivot rod 21 at one end extends through the corresponding side 18, and is latera ly disposed to form an arm 32. The

. plate 13 has a rigidly mounted eye 33, to

which is'secured one end of a helical spring 34. The opposite end of the helical spring is fastened to the extremity of the arm 32, and thus serves to hold the frame 20 in a normal position against the late 13. The arm 32 has depending there In a flexible member 35, consisting of chain or the like,-

and having at the end a ring 36 adapted to tened to an eye 40 rigidly mounted frame 20. At the end of the arm the arm 32 untll the ring the plate and the hood frame. A.

points of the a flexible member 41, consisting of a chain or the like, and having at the inner end a ring 42 adapted to engage studs 43 or 44 to hold the window open against the tension of the spring 39.

\Vhen the frame 20 is in position against the plate 13, thus closing the opening 14, the window can be held open by causing the ring 42 to engage the stud 43. This permits a smaller ventilating opening to be unobstructed.

\Vhen the frame 20 is in position a ainst the hood frame, the window can be hel open by engaging the ring 42 with the stud 44. In this Way, the largest ventilating openin is provided. It will be-seen that three a justments are possible. I

Having thus described my invention, I claim as new and desire to secure by Letters Patent I 1. A ventilator having an opening, a closure movably mounted at said openmg, and havin an openin therethrough, and a further c osure mova ly mounted at said openingof said first closure.
